CONVEYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 602,085, dated April12, 1898.

Application filed October 5 1897. Serial No. 654,100. (N0 model.)

To all whom it may concern.-

Be it known that I, FRANK B. KNIGHT, a citizen of the United States, anda resident of Brooklyn, in the county of Kings and State of New York,have invented certain new and useful Improvements in ConveyingApparatus, of which the following is a specification.

The object of my invention is to so con struct, connect, and operate abucket as to adapt the same for excavating hard material and at the sametime for being dumped at any desired point.

In the accompanying drawings, Figure 1 is a side view of the bucket andsuspending apparatus in carrying position. Fig. 2 is a side View of thesame in dumping position and also of one of the towers. Fig. 3 is an endFig. 4 is a plan view of a portion of the same.

1 and 2 are the side plates of a bucket. 3 is the plate constituting thebottom, back, and top of the same.

4 is the front edge, which is armed by the front teeth 6. The sideplates 1 and 2 are also armed by the side teeth 7. The form-of thisbucket and the inclination and form of these teeth are as shown inthe-drawings, so that when the bucket rests upon the bank and is pulledforward by the fall-block 12 the teeth will enter and loosen up thedirt,so that it will be scooped into the bucket by the edge 4.

9 9 are pivots by which the unjointed rigid bail 10 11 is pivoted to theside plates 1 and 2 in such position that the center of gravity of thebucket lies between the pivots 9 9 and the forward edge 4, causing thebucket when free to revolve upon said pivots to assume the positionshown in Fig. 2.

12 is a fall-block.

13 13are eyebolts connected with the bail member 11 and to which ispivoted the latchframe 17 17, provided with the shoulders 15, adapted toengage with ashoulder 16 on the top of the bucket and hold the same. inthe carrying position shown in Fig. 1. 18 is a rod extending between themembers 17 17, to which rod is pivoted the trigger 19 2O 21. Theprojections 21 21 on this trigger rest on the top of the bucket, whichforms a fulcrum, so

engage the shoulders 15 from the shoulder 16 and permit the bucket torevolve from the carrying position'of Fig. 1 to the dumping position ofFig. 2. 1

22 and 23 are stops secured to the side plates of the bucket, so as tolimit the extent of rotation in each direction.

24 24 are pockets adapted to hold handles, if desired, said pocketsbeing located in the back plate 3 of the bucket, so that the handleswill be removed from the edges, and the hands of the operator will thusbe removed from the side of the bank when working close up to a bank.

25 is a carriage traveling on the cable 26.

27 is the endless traction-rope for moving the carriage. I

27 is a rope for supporting the fall-rope carriers 27 27 is a horn fixedto the carriage by which said fall-rope carriers are also supported.

28.is a fall-rope supported on the carriage by the sheaves 30 and 32 andsecured to the tail tower at 29. The fall-rope passes under the sheave31 of the fall-block.

33 and 34 are pendent hooks pivoted to the carriage by the pin 30. Eachof these hooks has a mouth 35 and an incline 36 below the mouth.

37 37 are mouth-guards pivoted on one side of the mouth at 37, andthence inclining downwardly and resting loosely on the lip 35 at theopposite side of the mouth.

38 is a trigger-chain attached at one end to the trigger, as alreadydescribed, (or it may be attached directly to the latch and the triggeromitted, as shown in dotted lines,) and carrying at its opposite end across-bar 39. The

side members of the fall-block 12 are extended horizontally, so as tosupport the members 39 the traction-rope 27 and hauls in on the fallrope28. As the fall-block is thus raised the cross-bar 39 strikes againstthe inclined surfaces 36 and swings the hooks 33 and 34 into theposition shown in dotted lines, Fig. 2. Then the cross-bar 39 strikesagainst those parts of the guards 37 37 overhanging the lips and raisesthe guards. Then the crossrod proceeds above the lips 35 and the hooks33 and 34 drop into the position shown in full lines, Fig. 2. Then theattendant stops hauling in on the fall-rope and pays out the same,

so as to lower the fall-block. As the fallblock descends, however, thecross-bar is now held in the mouths 35. has descended a certaindistance, by its movement relatively to the dumping-member actuator 34.the chain 38 is drawn taut, so

as to pull the trigger and trip the latch 17. Thereupon the bucket dumpsbecause the center of gravity in the position shown in Fig. 1 is aboveand to the right of its pivotal supports 9. The operator now again haulsin on the fall-rope and this time raises the fallblock as far asindicated in dotted lines in Fig. 2, so as to lift the crossbar 39 outof the mouths 35 far enough to permit the guards 37 to drop into theirnormal position, as shown in dotted lines in Fig. 2. Then the fall-blockis allowed to descend, and as it descends the downward]y-inclined guards37 prevent the cross-bar 39 from being caught in the months 35, so thatthe fall-block can be lowered to the ground at any point of the spandesired.

When this is done, the teeth 6 strike the ground first and the bucketwill rotate in the bail 10, so as to rest upon its bottom 3. Then bymoving the carriage 25 toward the head tower and at the same timelowering on the fall-rope the bail 10 will be caused to drop forwarduntil the latch 17 rengages with the 'top of the bucket, and the bucketis thus rigidly held by the rigid bail 10 and the rigid latch 17, sothat it will fill itselt when pulled along the ground by the fall-block.

From the above description it will be understood that the chain 38constitutes a dumping member and the hooks 33 and 34 aclumping-memberactuator. These and'otherparts,

however, are so arranged and combined as to dift'er from theconstruction shown in Miller patents Nos. 525,08; and 551,869, and I donot desire to be understood as claiming the construction shown in eitherof said Miller patents.

I claim 1. In a hoisting apparatus, in combination, a fall-block, abucket pivotally sustained by said fall-block with its center of gravityabove said pivots, a latch whereby said bucket is maintained in anon-dumping position, a

dumping member adapted for disengaging When the fall-block said latchand a dumping-member actuator relatively to which said fall-block has amovement; said dumping member and actuator being adapted to interlock asthe fall-block descends, substantially as described.

2. In a hoisting apparatus, in combination, a fall-block, a bucketpivotally sustained by said fall-block with its center of gravity abovesaid pivots, a latch whereby said bucket is maintained in a non dumpingposition, a dumping member adapted for disengaging said latch and adumping-member actuator relatively to which said fall-block has amovement and a carriage supporting bothsaid fallblock and saiddumping-member actuator; said dumping member and actuator being adaptedto interlock as the fall-block descends, substantially as described.

3. In a hoisting apparatus, in combination, a fall-block, a bucketpivotally sustained by said fall-block with its center of gravityabovesaid pivots, a latch whereby said bucket is maintained in a non -dumpingposition, a dumping member adapted for disengaging said latch, adumping-member actuator relatively to which said fall-block has amovement and a trigger connected with said latch and said dumpingmember; said dumping member and actuator being adapted to interlock asthe fall-block descends, substantially as described.

4.. In a hoisting apparatus, in combination, a fall-block, a bucketpivotally sustained by said fall-block with its center of gravity abovesaid pivots, a latch whereby said bucket is maintained in a non dumpingposition, a dumping member adapted for disengaging said latch and adumping-member actuator relatively to which said fall-block has amovement and a rest connected with the fall-block whereby said dumpingmember is normally supported substantially as described.

5. In a hoisting apparatus, in combination, a fall-block, a bucketsustained by said fallblock, a latch whereby said bucket is maintainedin a non-dumping position, a dumping member adapted for disengaging saidlatch, a dumpi n g member actuator relatively to which said fall-blockhas a movement and a guard whereby the mouth of said dumpingmemberactuator is controlled, substantially as described.

6. In combination, the hook 34, a projection therefrom carrying theinclined surface 36, a pivoted guard 37 lying across the mouth of saidhook, a member 39, means for reciprocating said member relatively tosaid hook and dumping mechanism connected with said member,substantially as described.
